Editor crashes when building lighting

get as far as “importing lighting 44%” then stops and crashes everytime, all is up to date, not sure what to do to fix it?

Hi BiscuitnGravy -

Can you please post a copy of your DXDIAG and let me know if the crash reporter pops up, if it does, please also include a copy of your Machine ID number?

Thank You

Hi BiscuitmGravy -

From your very brief description this sounds like a known issue. It is a conflict in the drivers for the Intel Integrated Graphics Drivers. Downloading the newest version of the drivers which can be found here:

Download Intel Drivers and Software will fix the crashing and allow you to continue to build lighting.

I should note that other users have reported that Intel (or their computer/laptop manufacturer) is telling them that they do not need an update. If this is the case, please check to make sure that your driver version is below the 15.36.21.64.4222 driver number. If it is at that driver number and you are still having this issue, please let us know. If not, one user had to force install the new update by downgrading his driver to an older version and then manually installing the driver linked above.

It could also be an issue with your computer not switching over to an included Nvidia or AMD Graphics Card when the Engine starts, but this is usually an issue on laptops only.

Hopefully this information will help you, if not feel free to respond to my comment above and I will attempt to help you further.

Thank You
